Description
Technical field
The present invention relates to oil gas well cementing operation field, furtherly, is related to a kind of high-temperature chlorine oxygen magnesium thermosetting resin gel
System and firming body and its preparation method.
Background technology
Oil-well cement is the portland cement of calcium oxide type, belongs to the cementitious material of the hydraulicity.It can be with water by certain
Ratio be mixed into cement mortar, and harden into underground with certain compression strength, the impervious Behavior of Hardened Cement Paste with durability, and
Can also there are wide adaptability and compatibility with various additives, extra material, density, intensity and hardening time are in a certain range
It is interior to realize design and control, can easily meet the needs of conventional cementing engineering, the general sealing as casing and cementing is situated between
Matter, is widely used for over more than 100 years in all kinds of operations such as oil drilling, completion, well workover, has ensured the smooth exploitation of oil gas field.
However, as various countries in recent years constantly increase the demand of clean energy resource, the especially unconventionaloil pool such as shale gas
Field constantly puts into exploitation, and conventional oil-well cement also exposes it and ensureing oil/gas well casing programme integrality, adapting to small
Deficiency in terms of gap environment and extensive perforation and acidfracturing treatment.Conventional hardened oilwell cement is a kind of brittleness material easily shunk
Material, its intrinsic hydration characteristics, use environment (high temperature, high pressure) and construction technology (high water-cement ratio, high fluidity) determine it
With several critical defects：High volume contraction, high filter loss and high brittleness.The volume contraction of cement mortar slurry causes cement sheath
It is cementing etc to cannot be guaranteed, it is also possible to form microgap, trigger formation fluid channelling.Foreign literature shows, ordinary cement slurry
Volume can be shunk more than 5% after 120h is conserved, while analog study shows, microgap of the cement sheath interface there are 0.01mm
Has channeling can occur.Under intense loading lotus percussion, cement sheath can rupture and form macroscopic cracking and interface high brittleness Behavior of Hardened Cement Paste
Destroy.And high leak-off make it that dehydration bridge blinding occurs for cement mortar in the construction process and dehydration shrinkage, cement mortar filtrate enter oil gas
After layer, payzone can be also polluted.Therefore, portland cement easily makes since the external force such as material deformation or underground high temperature, high pressure acts on
Behavior of Hardened Cement Paste crystal inside is undergone phase transition, and triggers microannulus, microcrack, influences the integrality of Behavior of Hardened Cement Paste.Downhole fluid also can at the same time
Behavior of Hardened Cement Paste is caused to corrode, each discontinuous running such as drilling well, completion, volume increase and production may all cause cement sheath and annular space sealing
Damage, causes annular space seal failure.Some preventions and remedial measure are all passivitys, and success rate is not high, and expense compares
It is expensive.For Tail Pipe For Complicated Deep Wells, ultra-deep oil/gas well, annular channeling often occurs, it is poor mainly due to cementing concrete ring bonding quality,
Stratum high pressure gas or water is caused to be altered along annular space microgap to well head or casing, and " weightlessness " of cement mortar during curing
Phenomenon also results in has channeling, and being continuously increased with the production time, and annular space situation with pressure is also continuously increased.Sinopec is in recent years
Also there is annular space situation with pressure the general light gone into operation successively, the gas field such as burnt masonry dam.The reason for causing annular space with pressure, has very much, but
Itself deficiency as oil well cement material is one of most important one factor.
Therefore, oil gas water breakthrough has become the difficulty that a urgent need of oil-gas field development solves after how preventing well cementation
Topic.Wherein, consider from material angle, seek to develop the developing direction that new gelling system is casing and cementing.
