在高凝油油藏的压裂施工中 ,对地层注入冷流体会使井底周围的原油冷却 ,导致原油析蜡或凝固 ,从而堵塞流动通道 ,降低裂缝的导流能力。因而采用自生热压裂技术 ,依靠生热剂发生化学反应所放出的热量来提高注入流体的温度 ,使井底压裂液的温度在施工期间高于原油的凝固点或析蜡点。在压裂过程中预测井筒温度的变化 ,以保证压裂液在进入裂缝后不会对裂缝和储层造成“冷伤害”是实施这一技术的关键。根据热平衡方程 ,建立了自生热压裂过程中井筒温度场的数学模型 ,采用隐式差分格式建立了数值计算方程 ,并对一口井进行了实例计算和分析。结果表明 ,采用自生热压裂技术能有效地提高压裂液的温度 ,防止高凝原油析蜡和凝固 ,避免储层伤害。

china Ocean Engineering 1994年第1期9卷 95-104页

作者： Liang Zheng Lecture, southwest petroleum institute, nanchong 637001, Sichun Province

-Based on the calculation model for the floating laying of the offshore oil pipeline, this paper analyses in detail the internal force, and deformation of the pipeline under a definite structural form (pipeline and buoy) and the way of pulling. The obtained results can be used for the buoy deployment, structure design, and the determination of pulling parameters (the pulling force of the cable and its length, etc.), providing an effective analysis method for floating pipeline-laying. A calculation example is given to show the related calculation process and the main results are analyzed and discussed.

-Considering both the seabed foundation and wave, an analytic model of 'J' type is proposed for offshore pipeline-laying. The governing differential equation is also obtained for the pipeline on the seabed and for the suspension sections. By utilizing weighted- residual method and dual iteration technique, an approximate solution is obtained, too. In the end, calculation examples are given for analyzing the changeable relationship among the major parameters.

As is well known that many decollement layers were developed in the Longmenshan thrust belt,Si-chuan Basin,china. Through field investigation,explanation of seismic profiles and analysis of the balanced sections,we can divide the decollement zones into 3 categories: (1) the deep level decolle-ment zones,including the crust-mantle decollement layer,intracrustal decollement layer,and presinian basal decollement layer. The main structural styles of their deformation are the crust-mantle decoup-ling detachment deformation,the basal ductile shear deformation,etc.; (2) the middle level decollement zones,including the Cambrian-Ordovician decollement layer,the Silurian decollement layer,etc.,the main structural styles of their deformation are the isopachous fold,the angular fold,the saddle struc-ture,and the combination styles of them; and (3) the shallow level decollement zones,including the Xujiahe Formation decollement layer of Upper Triassic and the Jurassic decollement layers,the main structural styles of their deformation are the thrust-nappe tectonic,the pop-up,the triangle zone ,the duplex,etc. Multi-level decollement zones not only made the Longmenshan thrust belt develop many different deformation styles from deep place to shallow place,but also made some local areas have the superimposition of the tectonic deformation apparently. This study indicates that the multi-level de-collement zones have a very important effect on the shaping and evolution of the Longmenshan thrust belt.

The Sebei gasfield is the largest biogas accumulation found in china and many reservoirs and seal rocks superposed on a syndepositional anticline in *** biogas charging and dissipating process and its distribution have been a research focus for many *** authors suggest a diffusing and accumulating model for the biogas,as they find that the shallower the gas producer,the more methane in the biogas,and the lighter stable carbon isotope composition of *** on the diffusing model,diffused biogas is quantitatively estimated for each potential sandy reservoir in the gasfield,and the gas charging quantity for the sandy reservoir is also calculated by the diffused gas quantity plus gas reserve in-place.A ratio of diffusing quantity to charging quantity is postulated to describe biogas accumulating state in a sandy reservoir,if the ratio is less than 0.6,the reservoir forms a good gas-pool and high-production layer in the gasfield,which often occurs in the reservoirs deeper than 900 m;if the ratio is greater than 0.6,a few gas accumulated in the reservoir,which frequently exists in the reservoirs shallower than 900 ***,a biogas accumulation model is built up as lateral direct charging from gas source for the sands deeper than 900 m and indirect charging from lower gas-bearing sands by diffusion at depth shallower than 900 *** this charging and diffusion quantitative model,the authors conducted re-evaluation on each wildcat in the central area of the Qaidam Basin,and found many commercial biogas layers.
