Introduction hydraulic fracturing process

Hydraulic fracturing process includes four aspects: hydraulic fracturing process is generally how long it takes? Hydraulic fracturing process of ceramic injection time will be long? Hydraulic fracturing process of ceramic concrete steps and the amount of fracturing a well.
Hydraulic fracturing process is usually two hours,  ceramic proppant  process is very short.
Hydraulic fracturing includes five steps:
1. Well and layer selection: the cost of fracturing a well is generally from 500 thousand to 1 million yuan, an oil reservoir with multi-layered general.
2. Hydraulic fracturing design
3. Preparing for Hydraulic Fracturing
4.  hydraulic fracturing :
According to different wells have different design requirements can be broadly divided into the following steps:
(1). Test pressure (pressure test): wellhead equipment, ground facilities for the testing process pressure capability.
(2). Join Preflush (pad fluid water activity): The aim is broken strata, causing cracks in certain geometries, to prepare for the entry of sand-carrying fluid can also clean the wellbore surrounding impurities.
(3).  Proppant  solution: its role is to be ground into the fracture proppant and brought to a predetermined position of the fracture, as well as extension of crack formation in the cooling effect.
(4). Replacement fluid: The aim is to promote the sand carrying liquid, be sent to a predetermined position.
(5). Shut: According to different designs of wells, typically 4-12 hours.
5. Back row: flowback fluid is carrying sand (plant-based plastic material) is discharged back to the wellbore in order to protect the formation. In this step will need breaker.
The amount of fracturing a well ceramic, based on the calculated fracture length and width. Generally 30-40 square, large amount of up to one hundred sixty seventy square.
