Following analyses of the abnormal high pressure distribution characteristics, based on the geological characteristics, tectonic stress field and physical simulation, we investigated the formation mechanisms of abnormal high pressure and its impacts on hydrocarbon accumulation in the Kuqa foreland thrust belt. The abnormal high pressure appears at the bottom of the Paleogene and obviously exists in the Triassic and Jurassic. However, the pressure coefficient in the Triassic and Jurassic is lower than that in the Cretaceous and at the bottom of the Paleogene. Horizontally, the abnormal high pressure distribution is characterized by E-W orientation zoning. The maximum pressure coefficient lies in the Kelasu-Dongqiu-Dina tectonic zones in the center of the Kuqa foreland thrust belt and decreases away from the tectonic zones. The formation of abnormal high pressure was mainly related with the intense tectonic compression in the Early Pleistocene time, and tectonic uplifting, undercompaction and hydrocarbon generation were secondary factors contributing to abnormal high pressure. Under the rapid and intense tectonic compression in the Early Pleistocene, the rock framework firstly undertook 1/4.of the compression stress and the other was borne by the pore fluids. Due to the presence of great seal of gypsum-salt or gypsum-mudstone beds in the Paleogene, the pressure of pore fluids increased rapidly and led to the abnormal high pressure in the Kuqa foreland thrust belt. The abnormal high pressure has important impacts on hydrocarbon accumulation. It is one of the necessary conditions for formation of large oil and gas fields in the Kuqa foreland thrust belt.

Jinning granodiorite and diorite deeply concealed in the central tarim Basin

The 72.0-m-deep Well Tacan 1 in the central tarim Basin is the deepest in China. Purplish gray medium-grained granodiorite containing dark gray fine-grained diorite xenolith is revealed at the base of the well (7169―72.0 m), and they are results of the Jinning magmatic activities. Trace-element geochemistry and REE profiles of both rock types are similar, indicating that they are calc-alkaline series I-type granitoid. Proxies of diorite signify the development of a magmatic arc due to subduction at ca. 12.0 Ma. The granodiorite was formed before 890―932.Ma. However, more study is needed to clarify if the arc diorite represents a ca. 300 Ma extension of the subduction or a reactivation during the orogenic collision event at ca. 900 Ma.

Paleomagnetic and rock magnetic studies on samples of 18 sites from the Creta- ceous marine sedimentary rocks in the Tongyouluke section, Akto County, southwest tarim, China show that the magnetic carriers of the Lower Cretaceous are dominated by hematite with some magnetite, while the magnetic carriers of the Upper Cretaceous are characterized by a combination of magnetite and titanomagnetite as well as hematite and goethite. Stepwise thermal demagnetization is performed and vector analysis is used to isolate magnetic components, which illustrates a single magnetic component or double magnetic components. The high temperature stable components are dual polarities and pass polarity test, reversal test and consistency test. The overall mean direction of the Lower Cretaceous is D = 2..0°, I = 4.1}0°, α95=6.5° with pole position at φ = 190.3°, λ=63.1°, dp=4.9°, dm=8.0°. The overall mean direction of the Upper Cretaceous is D = 2..1°, I = 39.4., α95=11.2. with pole position at φ =190.9°, λ=60.3°, dp= 8.0°, dm=13.4.. Compared with the inclination of the Early Cretaceous from red beds of north tarim, the contemporary inclination of southwest tarim is 10.0°±7.8° sharper, but it is still 8.1° ±8.9°, shallower than that of Early Cretaceous basalts in southwest tarim. Although these pa- leomagnetic data show slightly larger confidence limit, the paleolatitude of the marine Cretaceous tends to lie between that of terrestrial red beds and volcanic rocks.

The salt beds of Lower Tertiary developed in the mid-segment of Kuqa foreland fold belt, northern tarim basin. They considerably controlled structural deformation of the belt. Ac- cording to the field observation, seismic profile interpretation and drilling data, three different structural styles of supra-salt, intra-salt and sub-salt occurred in the Kuqa foreland fold belt. Su- pra-salt structural styles mainly include thrust faults and fault-related sags. Intra-slat structural styles essentially are salt-pillows, intra-salt faults and folds, and salt weld structures. Sub-salt structural styles mainly consist of imbricated thrust faults, duplex structures, pop-up and fault-related folds. It is indicated that great differences exist among supra-salt, intra-salt and sub-salt structures of Kuqa foreland fold belt. The salt-related structures were formed in the same structural stress field. The dynamic mechanism of the salt-related structures is mainly associated with gravitation, compression and plastic flow of salt beds.

Tacan 1 well (called TC1 for short) is an exploration well in the central part of tarim Basin, NW China and also the deepest on-land well in China so far. The strata revealed by this well covers upper to lower are Quaternary, Neogene-Eogene (without further classification), Cretaceous, Triassic, Permian, Carboniferous, Devonian, Silurian, Ordovician, Cambrian and Precambrian granodiorite. The stratigraphic section is relatively complete has systematically extracted cores. It is very precious for geological study In tarim. This paper provides its brief description. Some related problems are discussed.

Calculation of depth to detachment and its significance in the Kuqa Depression:A discussion

We analyze the excess area and depth to detachment method developed by Epard and Groshong （1993）, and apply it to the sand box model of Ge et al （2.04. to illustrate that inadequate consideration will affect the calculation of true depth to detachment. Using the data of Yu et al （2.06） to fit linear regression lines, we obtain the depths to detachment of Kela-2. Misikantage anticline and Dongqiu-8 structures, 115.74.m, 14.17km, and 75.4.km below the reference level （Cretaceous bottom） respectively with the excess area intercept equal to zero. However, the calculation results of depth to detachment in Yu et al （2.06） are based on excess area intercept unequal to zero.

Borehole stability in naturally fractured reservoirs luring production tests

Petroleum Science 2008年第3期5卷 247-250页

作者： Zhang Fuxiang Zhang Shaoli Jiang Xuehai Lu Rende Chen Mian tarim oil {2. company PetroChina Korla Xinjiang 834000 China petrochina company Limited Beijing 100011 China School of Petrnleuln Engineering China University of Petroleum Beijing 102249 China

Based on the plane of weakness theory, a model for predicting borehole stability in fractured reservoirs under different stress states was estiblisted and the equations for solving borehole stability were developed. The minimum downhole pressures required to maintain borehole stability under different natural fracture occurrences were calculated by using the data from a well in the Tazhong （central tarim） area, tarim Basin, west China. Several conclusions were drawn for naturally fractured reservoirs with a dip angle from less than 10° to greater than 30°. Application in three wells in the Tazhong area indicates that this model is practically useful.
