Neotectonic movement refers to the tectonic movement that has happened since the Cenozoic, which is the latest movement. It has the most important influence on the basins in west china, especially on the hydrocarbon accumulation in the western foreland basins. We determined the time of neotectonic movement in the Kuqa Foreland Basin, which began from the Neogene, and analyzed the patterns of movement, which were continuous and fast subsidence in the vertical direction and intense lateral compression. The structure styles are that the faulting is weakened and the folding is strengthened gradually from north to south. We studied the control of neotectonic movement on the hydrocarbon accumulation process and model in the Kuqa Foreland Basin with basin simulation technique. The largest subsidence rate of the Kuqa Foreland Basin reached 1,200 m/Ma during the neotectonic movement, leading to rapid maturing of source rock within 5.Ma and a large quantity of hydrocarbon being generated and expelled. The thick neotectonic strata can form high quality reservoirs with the proved gas and oil reserves accounting for 5. and 27% of the total reserves, respectively. 86% of the structural traps were formed in the neotectonic movement period. The faults formed during the neotectonic movement serve as important migration pathways and they exist in the region where the hydrocarbon reservoirs are distributed. Abnormally high pressure caused by the intense lateral compression, thick neotectonic strata deposition and rapid hydrocarbon generation provide driving force for hydrocarbon migration. The accumulation elements match each other well over a short period, leading to many large gas fields formed later in the Kuqa Foreland Basin.

Dongxin oil field entered super high water cut stage in late 1993, and problems appeared such as seriousshortage of backing sources and production declined year after year. The research on structural system ofoil field fracture, depositional system, development feature and the distribution of remaining oil waslaunched to solve these Problems. In this process, many techniques were developed and completed, suchas progressive exploration & development technique, reservoir description and prediction techniques forfracture transform zone, interactive automatic tracing and plotting in structural low and flat area, loggingrestricted reservoir inversion and elaborate reservoir description techniques, and enhanced the inner andouter exploration. Pertinent injection-production adjustments were taken in old block on the basis ofresearch on remaining oil. The production decline was controlled obviously, and the revived. development balance was realized in 1997. The old field that has been developed for 30 years revived.

Application of an analytic hierarchy process to hydrocarbon accumulation coefficient estimation

引用

petroleum Science 2010年第3期7卷 337-346页

作者： Gao Yongjin Liu Lifeng Liu Huimin Zheng Feifei Wu Li Zhou Jingjing Qu Dongfang State Key Laboratory of petroleum Resources and Prospecting China University of Petroleum Beijing 102249 China Geoscience Research Institute Shengli Oilfield SINOPEC Dongying 257061 China Laboratory of Integrated Geology and Geophysics Research China University of Petroleum Beijing 102249 China

The hydrocarbon accumulation coefficient is a key parameter in resources evaluation by genetic techniques. Methods of obtaining its value scientifically have always been an important factor influencing evaluation credibility. In this paper, the hydrocarbon accumulation system is evaluated quantitatively by establishing a hierarchy structure model based on an analytical hierarchy process. The hydrocarbon accumulation system of a higher exploration degree is selected as a calibration area and its hydrocarbon accumulation coefficient can be calculated using methods of hydrocarbon generation potential and reservoir-scale sequence. The hydrocarbon accumulation coefficient of a petroleum accumulation system can be gained by analogy of reservoir forming comprehensive evaluation results with the calibration area. The hydrocarbon accumulation coefficient of each petroleum accumulation system in the upper reservoir-forming combination of the Liaohe Western Sag can be obtained with this method. Practice shows that using the analytical hierarchy process to quantitatively evaluate the hydrocarbon accumulation system and then quantitatively predict the hydrocarbon accumulation coefficient decreases the influence of human factors in resources evaluation, and makes the resources assessment more objective and closer to the actual geological condition.
