梁112块沙四段薄互层低渗透油藏水力压裂工艺优化

梁112块沙四段薄互层油藏属于典型的高压、特低渗透油藏,具有油层多、单层薄、砂岩与泥岩交互等特点。常规压裂效果不理想。通过建立单井模型,确定了压裂应以增加裂缝的长度为主;利用FracproPT软件模拟优化加砂规模;根据油层物性特点优化射孔方案;配套应用粉陶降滤和控制缝高等技术优化了水力压裂工艺。2004年共对11口井实施了大型水力压裂,平均加砂量为42.5m3,平均加砂强度为1.6m3/m,累积增产原油达2.75×104t。     

Denying History: Comment.

Comments on an article by Eidelson and Eidelson (see record 2003-03645-004) which made an important contribution, at a critical juncture, to the discussion of international conflicts by identifying core dimensions that allow for the systematic examination of the problem. Their article also posed a danger that mirrors a disturbing trend in the public discourse about conflicts and injustice. In response to the recent escalation of international violence and years of mixed results of engagement in debates centered around grievances of injustice (such as the Palestinian-Israeli conflict), many politicians, pundits, and scholars have advocated addressing conflicts by separating them from the underlying grievances and the ongoing injustice.

砾岩储层精细描述中标准测井资料的应用

克拉玛依油田七区的标准测井资料是指使用标准电极系视电阻率测井、自然电位测井和井径测井,以相同的1:500深度比例尺及相同的横向比例进行测井作业所取得的资料.这种资料本来并不具备定量解释储层孔隙度和含油饱和度的能力,但这种资料占该区测井资料总量的比率高达34%.利用标准电极系视电阻率资料和岩心分析资料建立了视电阻率-岩性图版,利用自然电位减小系数α和岩心孔隙度分析资料φ建立了α-φ图版,根据综合测井资料求出标准测井视电阻率校正系数,进而确定了饱和度计算方程的参数.与相应的综合测井资料计算结果相对比,用该方法得到的孔隙度平均绝对误差及相对误差分别为1.85%和11.88%;含油饱和度平均绝对误差及相对误差分别为9.08%和24.75%.将该方法有选择地应用到该区砾岩储层精细描述研究中,弥补了缺乏综合测井资料无法进行测井储层评价及参数研究的缺陷.

Organic matter and nitrogen removal by an on site sewage treatment and disposal system

The performance of an on site sewage treatment and disposal system consisting of a septic tank, a gravel filter, a sand filter and soil absorption trenches operated alternatively, was studied in relation to organic matter and nitrogen removal efficiency. The system was simulated with the aid of a laboratory scale model. BOD₅ and SS removal efficiencies averaged 92.9 and 93.4% respectively. Substantial removal of nitrogen (up to 70%) was achieved due to nitrification followed by denitrification. Removal efficiencies were found to depend on the compaction characteristics of the filter media and the soil, the hydraulic loading applied and the flow conditions (saturated/unsaturated). The results indicate that the system under consideration is a feasible alternative for on site treatment and disposal of domestic sewage.
