Northwest Oilfield sand fracturing flowback process optimization achieved remarkable success
Northwest Oilfield Completion Test Management Center under the category of single well reservoir, sand size, design, optimize ground sand fracturing flowback process, single-

well process connection time shortened 12 hours, a single well to save costs 24 million.
Graded sand fracturing  and conventional domestic oil sand fracturing is common for low porosity and low permeability class of low-grade oil and gas reservoir development of an

important means. At the end of open fracturing production well testing requirements will initially appear Proppant  reflux, sand production and other issues, causing the ground

test equipment being eroded or even lead to accidents. To solve erosion problems and meet sand fracturing oil demand after the test production requirements, used in the past are

highly configurable flowback process structure, although the effect is good, but mainly used in oil-producing wells but there is overkill, high cost issue. Completion Test

Management Center flowback through the high-profile case of the use of process structure analysis of the scene, the design of safe and economical low profile sand fracturing

flowback process solutions. Low profile sand fracturing flowback process is relatively high configuration flowback processes, streamlined two sets of 70 MPa and a choke manifold

sets Desander. Jade North 1-7 wells No. VI Maigaiti a block Manan an appraisal well on the structure, the test reservoir bit Ordovician Yijianfang (limestone), the well using

sand acid fracturing completions . In acid fracturing construction, they used low profile sand fracturing flowback processes open wells flowback,Proppant flowback no reflow

phenomenon during the successful completion of the construction and subsequent acid fracturing test oil demand production tasks. Sand fracturing flowback process optimization

success.
Sand fracturing flowback level configuration process to further improve the sand fracturing completion reservoir reconstruction process, to effectively ensure the Tahe main

producing areas, tower, Jade North, bridges and other ancient blocks of low porosity and low permeability , gas exploration and development; according to the characteristics of

sand fracturing wells selectively block the use, greatly improving the timeliness and reduce costs.
