【摘要】：近年来,按照长庆油田公司“马岭下面找马岭”的思路,采油二厂加大了三叠系下部层系的勘探评价开发力度。环305、环82井区是近三年建产效果较好区块之一。马岭地区长8主要受西部及西南物源影响；在沉积上,与姬塬及西峰油田长8既有相似性,又有其特殊性。马岭地区长8主要发育长812油层,长812油层分布稳定,连通性好,规模落实,砂体呈现连片趋势。通过对近年该区探评井和产建井的实施效果的分析,环305-环56、环82井区、里148井区、木30井区是下步有利建产区。该区平面及纵向上非均质性较强,通过规模实施水平井,可提高钻遇一类油层概率。通过优化钻井方式、注水时机、压裂参数及前置酸可提高单井产能。从试油、试采、开发层系、开发方式、压力保持水平及合理单产入手,可以实现长期稳产,提高油藏采收率。
[Abstract]:In recent years, according to the idea of "looking for Maling under Maling" in Changqing Oilfield Company, the second Plant of Oil recovery has increased the exploration, evaluation and development of the lower layer of Triassic system. Huan 305, Huan 82 well area is one of the better production areas in the last three years. Chang8 in Maling area is mainly influenced by the western and southwest provenances, and is similar to Chang8 in Jiyuan and Xifeng oil fields, and has its particularity. Chang812 oil layer is mainly developed in Maling area, and Chang812 oil layer is stable in distribution, good in connectivity, implementation in scale, and the sand body shows a continuous trend. Through the analysis of the effect of exploration and evaluation well and production well construction in this area in recent years, Huan305-Huan56, Huan82 well area, Li 148 well area and Mu30 well area are favorable production areas for the next step. The horizontal and longitudinal heterogeneity is strong in this area. The probability of drilling and meeting a class of reservoirs can be improved by implementing horizontal wells on a large scale. The single well productivity can be improved by optimizing drilling method, water injection timing, fracturing parameters and preacid. Starting with oil test, production test, development series, development mode, pressure maintenance level and reasonable unit yield, long-term stable production can be realized and oil recovery efficiency can be improved.
