＜正＞The catalytic effects of reservoir minerals, catalyst nickel sulfate and hydrogen donor formic acid on aquathermolysis of Daqing heavy oil were evaluated through experiments *** results showed that H/C atom number ratio increase by,the content of saturates and aromatics increases by,the content of resins, asphaltenes and sulfur decreases by respectively with reservoir minerals and chemical agents working in a synergetic *** comparison with untreated oil sample. Pyrolysis gases collected in the experiment prove that the dissociation of week bonds of heavy components present in oil occurs in the presence of high temperature water vapor. Field testing results show that downhole catalytic aquathermolysis enhances oil and water recovery,raises oil/steam ratio and extends production time during steam stimulation,which proves that it is a effective technology for recovering heavy oil under steam injection circumstances.

作者： Wang YuxiaoExploration and Development Research Institute,Zhongyuan oilfield company,Sinopec Exploration and Development Research Institute Zhongyuan Oilfield Company Sinopec

Sinopec, Asia's largest refiner,announced on April 29 that its net first quarter profit skyrocketed almost 12-fold as it sold more refined oil and petrochemical products, cashing in on the international price hikes in oil during the period. However, analysts said the growth of china's second largest oil company is expected to recede in the second quarter as oil prices fall due to the end of the Iraq War. They still anticipate the company's full-year profit will increase by 15 percent or more on the back of a domestic oil market recovery.

Geodetic deformation severely affects the development of the oilfield and probably causes casing damage or abandonment of injection wells and producers. Therefore, it is meaningful to survey and study three-dimensional geodetic deformation in the process of the oilfield development. In order to study this issue, 11-year long term surveying of three-dimensional geodetic deformation has been carried out while developing Naner area in Daqing oilfield. Basic rules of 3.D geodetic deformation have been obtained through surveying. Results show that production and injection under high pressure may cause the changes of surface elevation, and geodetic deformation correlates with simultaneous formation pressure. Precautions and relative technological measurements have been put forward in the waterflood development in Naner region and provide theoretical guidelines for the production and casing preservation of the oilfield. Finally, surveying results are interpreted by porous elastic theory. Mathematical model to calculate 3.D geodetic deformation is put forward in the course of the oilfield development.

限定了井眼方向的待钻井眼轨道设计问题需要求解一个7元非线性方程组,通常使用的数值迭代方法有许多固有的缺点,提出了一个新方法──代数法:将原始非线性方程组化简成一个三元多项式方程组,再进一步归结为求一个10次多项式方程全部正实数解问题和一个二元线性代数方程组问题。给出了代数法的计算机实现方法,具有计算速度快、数值稳定性好、存储需求小等特点。代数法具有与解析法相近的良好数学性质,能够对问题是否有解做出事前判断;在问题存在多个解的情况下,能够正确求出全部的解。所使用的数学化简技巧能够推广应用到求解定向井、水平井的井眼轨道设计问题中,有重要的理论价值和应用前景。

利用真实的砂岩模型进行了单、双及组合模型 3.类型的水驱油实验 ,比较了有水敏、无水敏伤害时水驱油特征的差别 ,并对两种条件下的驱油效果进行了评价。研究结果表明 ,有水敏伤害的注入水驱油与无水敏伤害的地层水驱油相比 ,水驱油的入口压力增高 ,孔隙结构非均质性加强 ,水驱油绕流加重 ,驱油效率及波及系数降低 ;两种条件下的水驱油方式均为活塞式 ,残余油类型主要为绕流形成的簇状残余油。影响木钵区块延 10油层驱油效率的主要因素是储集岩的孔隙结构非均质性、水敏伤害、注水压力及加压方式。在对木钵区块延 10油层注水开发中 ,应加强对储层非均质性的研究 ,并注意采取有效的储层保护措施 ,提高油层采收率。在注水开发过程中 ,应逐渐提高注水压力 ,以最大限度地开采木钵延

下古生界碳酸盐岩是鄂尔多斯盆地天然气勘探的重要层系,20世纪末在盆地中部下古生界发现并探明的靖边气田,就是发育在奥陶系顶部的碳酸盐岩古风化壳气藏,也是该盆地目前的主力气田之一。中国石油长庆油田公司近期通过对碳酸盐岩成藏机制的不断深化研究和不懈勘探探索,在鄂尔多斯盆地中央古隆起东侧地区发现了奥陶系中组合岩性圈闭的碳酸盐岩含气新类型,其在储层发育特征、圈闭成藏机理及气藏分布规律等方面均明显有别于靖边地区的古风化壳气藏:①储层类型主要为白云岩晶间孔储层,其发育受控于颗粒滩沉积微相及古隆起东侧特殊的白云岩化作用条件;②圈闭类型主要为岩性圈闭,成因受控于短期海侵形成的区域岩性相变和燕山期盆地东部抬升的构造背景;③气藏呈现出环中央古隆起区域性分布的特征,形成多层系叠合含气、大范围带状展布的岩性圈闭有利成藏区带。对奥陶系中组合成藏新领域研究认识的深化,推动了天然气勘探思路的转变,对于今后鄂尔多斯盆地新领域研究、勘探方法、勘探方向等都具有重要的启示。
