In order to improve the drilling speed, lower the costs of development and solve the challenge of economies of scale development in sulige gas field, the key techniques research on long horizontal section of horizontal well drilling speed are carried out. Through analyzing the well drilling and geological data in study area, and supplemented by the feedback of measured bottom hole parameters provided by underground engineering parameters measuring instrument, the key factors restricting the drilling speed are found out and finally developed a series of optimum fast drilling technologies of horizontal wells, including exploitation geology engineering technique, strengthen the control of wellbore trajectory, optimize the design of the drill bit and BHA and intensify the drilling parameters.

Shale Gas Reservoirs

Systematic research and evaluations of shale gas reservoirs are critical in shale gas exploration and development. Previous studies in this field mainly depend on experimental analysis that is often overly simplified. Here, we report an integrated geological and engineering method that combines the lithofacies division system with an identification and evaluation technology from the micro to macroscale. This method has been successfully applied in field sites. The key achievements of this method include the following: 1 Lithofacies refers to the rock or rock assemblage formed in a specific depositional environment that has experienced a certain degree of diagenesis, which is a comprehensive term that contains information about the lithology, physical properties, gas content and fracturability. With the main rock type or several rock types combined as the basic name, the shale lithofacies are classified and named by highlighting particular characteristics such as total organic carbon (TOC) and content of brittle minerals. 2 Based on the lithofacies classification and constrained by the equivalent sequence interfaces or thin layer interfaces, the organic matter-rich shales in the Upper Ordovician Wufeng Formation to the Lower Silurian Longmaxi Formation in the Fuling gas field are longitudinally divided into 7 shale lithofacies. Furthermore, the organic carbonrich, high-silicon lithofacies is identified as the most favorable type for shale gas reservoirs. 3 A set of marine shale lithofacies identification technologies was created using cross-referenced scales of conventional logging and image logging, as well as logging summarization. Lastly, 4 the lithofacies technologies reported here have been successfully applied in multiple areas, including in the south and southeast of the Sichuan Basin and the Pengshui area. Applications in these areas include shale formation comparison and analysis, monitoring and analysis of horizontal well drilling, and assessment of fracturing stages in horizontal sections. The lithofacies technology is proven to be efficient and applicable for comprehensive shale gas reservoir evaluation.

AbstractShale gas reservoirs have been successfully developed due to the advancement of the horizontal well drilling and multistage hydraulic fracturing techniques. However, the optimization design of the horizontal well drilling, hydraulic fracturing, and operational schedule is a challenging problem. An ensemble-based optimization method (EnOpt) is proposed here to optimize the design of the hydraulically fractured horizontal well in the shale gas reservoir. The objective is to maximize the net present value (NPV) which requires a simulation model to predict the cumulative shale gas production. To accurately describe the geometry of the hydraulic fractures, the embedded discrete fracture modeling method (EDFM) is used to construct the shale gas simulation model. The effects of gas absorption, Knudsen diffusion, natural and hydraulic fractures, and gas–water two phase flow are considered in the shale gas production system. To improve the parameter continuity and Gaussianity required by the EnOpt method, the Hough transformation parameterization is used to characterize the horizontal well. The results show that the proposed method can effectively optimize the design parameters of the hydraulically fractured horizontal well, and the NPV can be improved greatly after optimization so that the design parameters can approach to their optimal values.

Abstract Multistage fracturing and multi-clusters with long lateral fracturing were applied during developing the WeiYuan shale gas field, and the fracturing parameters were variable obviously for the fracturing lateral, perforating clusters, pumping rate, fracturing fluid volume and proppant quality. In this paper, the 3D geological model of a WeiYuan shale gas pad was used to simulate and optimize the fracturing parameters of the shale gas horizontal wells. The simulating results show that there is a reasonable matching relationship between different fracturing lateral length and the perforating clusters, and there is an optimal fluid volume and proppant quality. As the length of the fracturing lateral and the number of clusters increase, the spacing of horizontal wells need to be reduced reasonably. With the purpose of fracturing parameters optimization for WeiYuan shale gas horizontal wells, it is recommended to increase the number of perforation clusters, increase the treating rate, and use the reasonable fluid volume and proppant quality for different fracturing lateral. The research results of this paper have guiding significance for the optimization and treatment of fracturing shale gas horizontal well.
