摘要:
對大慶長垣扶余致密油藏水平井、導眼井或鄰井測井和取心資料分析,搞清了水平井與直井的測井響應特征和差異,建立了井眼軌跡與地層幾何關系確定方法和步驟。在“七性”參數評價成果基礎上,總結了水平井甜點段、射孔位置劃分原則和方法。通過對扶余油層已試20口水平井產能影響因素分析,優選水平段長度、有效孔隙度、含油飽和度、脆性指數和砂體厚度等參數,采用類比法建立了水平井產能預測模型。研究成果對水平井射孔位置、壓裂段確定等工程設計提供了重要依據,對大慶長垣扶余致密油增儲上產具有重要意義。
Abstract:
How to use horizontal well LWD and Wireline logging data to determine the relationship between horizontal well borehole trajectory and stratum, calculate reservoir parameters, preferably select sweet spot section for fracturing, etc., has become an urgent problem to be solved in Fuyu tight reservoir of Daqing Changyuan oilfield. Through the analysis of the logging and coring data of horizontal well, pilot well or adjacent well, the logging response characteristics and differences of horizontal well and straight well were determined, and the methods and workflow of obtaining the relationship between borehole trajectory and stratum were established. Based on the evaluation results of “seven characters ” parameters, the principle and method of evaluating the dessert section and perforation position of horizontal well were summarized. Moreover, based on the test data of 20 horizontal wells in the study area, the factors affecting the capacity were analyzed, the parameters such as horizontal section length, effective porosity, oil saturation, brittle index and sand body thickness were optimized, and the productivity prediction model of horizontal well was established by analogy method. The research results provide an important basis for engineering design such as perforation position and fracturing section determination of horizontal well, which was of great significance to reserve and production increment of Fuyu tight oil in Daqing Changyuan oilfield.
